Description

[Detailed Description of the Invention] The present invention relates to an improvement of a cylindrical fuse mounting device for mounting a cylindrical fuse.

Generally, a cylindrical fuse installation device consists of a pair of fork-shaped clips fixed to a base made of an insulating material such as synthetic resin, and the conductive cylindrical body of the cylindrical fuse is inserted into both clips. Therefore, a cylindrical fuse can be installed. The cylindrical fuse is usually attached to the cover to prevent electric shock and to be easily inserted and removed.

The cylindrical fuse is fixed to the panel surface of the switchboard while attached to the mounting device. A large number of cylindrical fuses are fixed adjacent to each other on the panel surface, and fuses with different rated currents are also fixed irregularly. Even though the rated currents of the cylindrical fuses differ, the mounting devices have the same configuration.
For this reason, each cylindrical fuse is attached with an application name plate so that it can be identified for which purpose the cylindrical fuse is used. The nameplate is usually attached to the cover. Also, when you remove the cylindrical fuse (cover) from the base, you can see which base it corresponds to.
A usage name plate is affixed around each cylindrical fuse on the panel surface of the switchboard.

However, there are the following disadvantages. That is, electric wires are connected to the fuse mounting device on the power supply side and the load side. Application nameplates must be affixed in locations that avoid electrical wires, and are located far away from the corresponding fuses, making them difficult to identify. Another disadvantage is that the application name plate must be affixed to the switchboard, making it impossible to increase the packaging density of the cylindrical fuse mounting device, and that the position of the name plate cannot be determined at the design stage, making it impossible to standardize.

The present invention was developed in response to the above-mentioned problems, and its purpose is to provide a cylindrical fuse mounting device that can easily identify the purpose of the cylindrical fuse, increase packaging density, and standardize the design. Our goal is to provide the following.

The feature of this invention is that a nameplate mounting surface is formed on the cover mounting side in the direction of wire extraction of the insulating base that constitutes the mounting device, and the nameplate is attached to this nameplate mounting surface and also to the cover. There is a particular thing.

An embodiment of the present invention is shown in FIGS. 1 and 2.

FIG. 1 shows a state in which the insulating base 1 and cover 2 are combined, and FIG. 2 shows a state in which the cover 8 is removed from the base 1. A pair of clips 2a, 2 are attached to the bottom surface of the insulating base 1 formed in the shape of a rectangular parallelepiped using an insulating material.
b is fixed with screw 3. Clip 2a, 2
b is made of a conductive material and is formed to have a pair of contact pieces that are symmetrical and bent into a waveform to provide elastic force. A square groove 4 is formed approximately in the center of the bottom surface of the base 1. A mounting hole 5 is bored in the center of the rectangular groove 4 and penetrates through the back surface for mounting on a switchboard or the like. The square groove 4 is provided to prevent the head of a screw (not shown) for attaching to a switchboard etc. from hitting the cylindrical fuse 8 when the cylindrical fuse 8, which will be described later, is attached to the clips 2a and 2b. It is something. Square holes 6a and 6b are bored in both walls in the width direction of the base 1, into which electric wires (not shown) are introduced when connecting them to the clips 2a and 2b. Also, base 1
Trapezoidal grooves 7a and 7b are provided on the upper edges of both walls in the longitudinal direction, and a nameplate mounting surface 13 is formed at one end in the width direction. The mounting surface 13 is formed on the cover mounting side of the insulating base 1 in the direction in which the electric wires are drawn out. A nameplate 14B is attached to the mounting surface 13.

On the other hand, a cover 9 that holds the fuse tube 8 is made of a transparent insulating material, and a T-shaped handle 11 is provided on the top surface of a rectangular flat plate 10. The T-shaped handle 11 is provided at one end of the flat plate 10 in the longitudinal direction and approximately at the center in the width direction. Further, a nameplate 14A is attached to the other end in the longitudinal direction. A U-shaped cylindrical holder 12 is provided on the lower surface of the flat plate 10. The diameter of the cylinder of the cylindrical holder 12 is approximately equal to that of the conductive cylinder portion 8a of the cylindrical fuse 8, and the length is slightly longer than that of the insulating cylinder portion.

The fuse attachment device according to the present invention has the above-mentioned configuration, and when the cylindrical fuse 8 is attached to the cover 10, the cylindrical fuse 8 is attached to the cylindrical holder 12.
Hold it in a loosely fitted state.

After attaching the cylindrical fuse 8 to the cover 9 as described above, when the cover 9 is placed in the state shown in FIG. The state shown in Fig. 1 is reached, and the assembly of the fuse installation is completed.

As described above, the cylindrical fuse mounting device according to the present invention has a nameplate mounting surface 13 on the cover attachment side of the insulating base 1 in the wire drawing direction, and the nameplate 14B is attached thereto, so that the cylindrical fuse 8 and the base It becomes easy to identify the correspondence of item 1, and it is possible to prevent incorrect attachment. Furthermore, since there is no need to attach a name plate to the panel surface of the switchboard, it is possible to standardize the design and increase the packaging density without having to take connection wires into consideration.

Incidentally, the present invention can be similarly applied to a structure in which two cylindrical fuses 8A and 8B are inserted into one insulating base 1 as shown in FIG.

As explained above, according to the present invention, the cylindrical fuse and the base can be easily distinguished, and the design can be standardized and the packaging density can be increased.
